SIP scanners
Mango:
Yes, there were some reports some time ago that Obihai was implementing some of the methods suggested by users in this thread. :)
carl:
Since there are a few people who still do report the same problems I wonder whether Obi 202 is now less susceptible than obi100 or 110 and or whether those having problems did all the firmware upgrades.
Mango:
It's entirely possible. Anyone with an OBi202 connected directly to a modem (no double-NAT) want to test the type of NAT that its router employes?

I know it has been a while since any one posted in here but I have just received what I think is more SIP scanners.
From my call history they are showing "from 'abc' sp1(abc)" and "from 'us' sp1(us)"
My question is if I tweak my string as shown below, should that block these?
{(?|x|xx|xxx|xxxx|xxxxx|xxxxxx|us@@|abc@@):},{ph,ph2}
Thanks for all of your time and advise.

ddgiant – welcome to the forum.
You are on the right lines, but the format is a bit more tricky. For example “abc” followed by something or nothing would be “abc@.” The dot is important!
The following string should work:
{(?|x|xx|xxx|xxxx|xxxxx|xxxxxx|u’s’@.|abc@.):},{ph,ph2}
A further complication is that the “s” is a reserved character, so it needs to be enclosed by single apostrophes.
There are other ways to defeat scanners as detailed here:

The “Oleg Method” is highly recommended.
